№6.11 (с. 31)
Условие. №6.11 (с. 31)
скриншот условия
6.11 В цепь последовательно включены резисторы сопротивлением 14, 20 и 48 Ом. Какое напряжение будет показывать вольтметр на каждом резисторе, если сила тока равна 0,25 А?
Решение. №6.11 (с. 31)
Дано:
$R_1 = 14$ Ом
$R_2 = 20$ Ом
$R_3 = 48$ Ом
$I = 0,25$ А
Найти:
$U_1$ - ?
$U_2$ - ?
$U_3$ - ?
Решение:
Поскольку резисторы соединены последовательно, сила тока во всех участках цепи одинакова и равна общей силе тока:
$I = I_1 = I_2 = I_3 = 0,25$ А.
Для нахождения напряжения на каждом из резисторов воспользуемся законом Ома для участка цепи:
$U = I \cdot R$
Теперь рассчитаем напряжение для каждого резистора отдельно.
1. Напряжение на первом резисторе ($R_1 = 14$ Ом):
$U_1 = I \cdot R_1 = 0,25 \, \text{А} \cdot 14 \, \text{Ом} = 3,5 \, \text{В}$
2. Напряжение на втором резисторе ($R_2 = 20$ Ом):
$U_2 = I \cdot R_2 = 0,25 \, \text{А} \cdot 20 \, \text{Ом} = 5 \, \text{В}$
3. Напряжение на третьем резисторе ($R_3 = 48$ Ом):
$U_3 = I \cdot R_3 = 0,25 \, \text{А} \cdot 48 \, \text{Ом} = 12 \, \text{В}$
Ответ: напряжение на первом резисторе составит 3,5 В, на втором – 5 В, на третьем – 12 В.
